Lohit Vijayarenu updated HADOOP-3948:
-------------------------------------
Attachment: HADOOP-3948.patch
Thanks Konstantin. Updated patch with all your inputs. For
bq. In case of FSEditLog.rollEditLog() you call it.remove() to remove
StorageDirectory in which a file cannot be created, but never
incrementCheckpointTime().
This was the case in trunk also, we did not increment checkpoint. I would like
to fix this in another JIRA along with to investigate if we miss this case any
other place. HADOOP-4045
